How to solve 1 and 2?

The following matrix projects 2-vectors onto the unit vector v =
(U1, V2):
P = vy"
= | °1
Also recall that the matrix I – P projects vectors orthogonal to v.
1. Find the two eigenvalues and corresponding eigenvectors of P. Do the same for I – P. You should be able to do all this without writing
down any characteristic equations.
2. Find a diagonalization of P. Please simplify matrix inverses.
3. Find a diagonalization of I – P. Again simplify matrix inverses.
-
4. You should have found that P and I – P are similar matrices. Use your diagonalizations to write I – P in the form of a product of P
-
with several other matrices (you do not need to simplify the product).
